The cuboid frame can be hollow structure, also can not be hollow structure, but the requirement is that central access and negative pressure extraction circulation circuit certainly need not communicate, and the mud of bottom is more, so we have increased aeration structure for the air current can be washed away the osmotic membrane surface, improves the filtration efficiency of the osmotic membrane of bottom, and the osmotic membrane on upper portion generally does not have mud to adhere to, so need not join in marriage aeration structure alone, only need the air current of bottom float the back and wash along the band can.
Furthermore, the central passage is of a hollow structure, each aeration hole is connected with an aeration pipeline extending along the width direction of the rectangular frame, and a plurality of air holes are formed in the wall surface of the aeration pipeline facing upwards.
Because the osmotic membrane is the strip, the fibrous form, is to cuboid frame width direction extension, so through the cooperation of the aeration pipeline and the air vent that width direction set up for gas can erode the osmotic membrane.
The aeration pipeline penetrates through the side edge of the cuboid frame and then extends downwards, and the end part of the aeration pipeline is closed to form the aeration pipeline fixed on the frame.
Further, four prisms that the cuboid frame set up along vertical direction extend downwards and form the support prism.
Further, the central passage is connected with the aeration inlet.
Further, the negative pressure extraction hole is connected with a water suction pump.
Furthermore, the bottom of the sedimentation tank is provided with a fixing hole matched with the support prism.
Through the design of the support prism and the fixing hole in the sedimentation tank in a matched mode, the whole frame can be better fixed at the bottom of the sedimentation tank.
Further, each first through hole is arranged right above the aeration hole.
The aeration range is limited, so that the aeration effect is improved.
Has the advantages that: compared with the prior art, the utility model has the following advantages:
by adopting the design scheme of the utility model, the filtering effect of the continuity of the permeable membrane can be improved through the structure of matching the aeration structure and the strip-shaped permeable membrane, and the design of the support prism is added, so that the rectangular frame can be better fixed at the bottom of the sedimentation tank.
